When you book a trip with us, there would be a deposit required (30% – 50% of total price). You can choose to deposit via direct bank transfer, Onepay (Credit card online payment) or Authorization letter with relevant bank fee request. The most popular one is OnePay with detail Guideline and Term, Conditions. The balance of the trip can be paid when you arrive in Vietnam by cash or credit card. It is recommended to visit our sales office in Cat Ba Island for payment and other details.
